Working machine system and working machine

Abstract

A working machine system may include a working machine, a working machine holder, and a detection mechanism configured to detect whether the working machine is held by the working machine holder. The working machine may be configured to be switched between a first state and a second state in which a predetermined switching manipulation is required to switch to the first state. When the detection mechanism detects that the working machine is not held, the working machine may switch from the first state to the second state in response to the working machine being unattended for a first predetermined time period. When the detection mechanism detects that the working machine is held, the working machine may switch from the first state to the second state in response to the working machine being unattended for a second predetermined time period which is longer than the first predetermined time period.
